Bro i was running map 12 on the JB3. (am fully modded hahaha)
Map 7 on the JB4 is only 16.5 psi. I was running 18 before DAILY with nothing wrong. will see what happens

Sorry to hear about your car. I know the feeling....sucks!

As for the JB3/JB4, do you know what the timing difference is between JB3 map 12 & JB4 map 7? They could be running significant timing difference and might be more critical on octane. Increasing time while keeping the same boost can make significant power increases.

Is everything 100% with your Meth Inj? Were you experiencing any misfires recently?

I just got my oil delivered. I broke down and got the OEM oil change kit + filter. Let me know when you're ready to do it. I'm all set

I'm going to break down and just get 7 quarts at Autozone when I get off work. Going to change it when I get home. PM me if you want to do it today...I should be free until like 7 or 8. I'm free tomorrow too, and it shouldn't take too long since you're at stock height too

I'm going to have to jack my car up and slide a rhino ramp under haha...need to build some extensions for my rhino ramps
